The Lowdown

Alright folks, Rusty here. Let's get into what’s on offer for the region. There’s going to be a significant wait before we see the good stuff, but there is something special to wait for.

Thursday morning the 13th is where we kick off the action, but it’s not a day for the faint of heart. Jaconé is showing a solid 7ft of S swell at 12 seconds. The combined energy is strong at 1467. It’s glassy, absolutely clean, thanks to a NNE breeze at only 3 mph. The water is sitting at a touch warmer than normal (74°F). But this is serious power – this is a spot for experienced surfers only. Crowds are possible here, so time it right.

The period from Thursday afternoon through the weekend is pretty desperate. Despite some decent swell sizes, the timing and conditions are off, and you’re looking at marginal to poor quality. Best to keep the board in the car.

We get a glimmer on Monday morning the 17th. Clean 5ft E swell at 8 seconds, with a moderate offshore breeze from the NE at 12 mph. The energy has dropped to moderate (452), so it won't be as powerful. It’s a much more friendly, manageable size for intermediates. It won’t be a classic, but it’s rideable.

Then we hit the desert. From Tuesday the 18th through to Friday the 21st, the swell takes a real dive in size and quality, with only tiny, poor-condition waves on offer. A blank run of about 4 days.

Saturday morning the 22nd brings a tease: 4ft S swell with glassy conditions. It’s clean, but small and inconsistent.

Now, hold onto your leashes, because the real highlight arrives on Sunday the 23rd. This is the standout morning. We’ve got clean, 5ft SSW swell with a period of 11 seconds, and the wind is dead calm, completely glassy. The combined energy is moderate at 504. This is that rare magic window where the conditions are as good as they get. The consistency should be decent, and the clean lines will make for some memorable rides. This is the one to circle on the calendar.

Monday the 24th keeps the energy flowing with a solid 6ft S swell at 13 seconds, producing strong energy (986) and clean conditions. It’s great, but the Sunday morning is the real king.

Tuesday the 25th ramps things up again with a punchy 8ft SSW groundswell at 13 seconds. The combined energy shoots up to strong (1794). The wind is cross-offshore and clean. This one is definitely for the experienced crew again – serious power and size on offer. The afternoon, however, looks like it might be a bit too big for the spot, so stick to the morning.

Wednesday the 26th sees another beautiful morning with 8ft S swell and dead calm, glassy conditions. Again, this is expert territory with a strong energy reading (1771), but the quality is undeniable.

The final notable morning is Thursday the 27th. A very long period groundswell from the S at 15 seconds rolls in at 5ft. The energy is strong (1813), and the wind is offshore and clean. That long period means it will grind in with real power – best suited for the more lined-up sections of the break, not a mushy beach.

Friday the 28th closes things out on a good note with another clean morning: 5ft S swell at 12 seconds and light offshore winds. A great way to end the run.

The best of the best? No contest: Sunday morning the 23rd. Glassy, clean, and a beautiful size that lets you actually enjoy the power. Get after it.

Rusty.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
